Electroplating prevents

Options

A. Current
B. Chemical effect
C. Rusting
D. All

Answer

**Step-by-Step Solution:**

1. **Understanding Electroplating**: Electroplating is a process where a metal object is coated with a layer of another metal using the process of electrolysis. This is done to enhance the appearance, prevent corrosion, or improve other properties of the object.

2. **Components of Electroplating**: The electroplating setup consists of a beaker containing an electrolyte solution, two electrodes (anode and cathode), and a power source (battery). The object to be plated is connected to the cathode (negative terminal), while the anode (positive terminal) is typically made of the metal that will be deposited onto the object.

3. **Electrolysis Process**: When electric current passes through the electrolyte, metal ions from the anode dissolve into the solution and are deposited onto the cathode. This process is driven by the chemical effects of electric current.

4. **Prevention of Corrosion**: One of the main benefits of electroplating is that it prevents rusting and corrosion of the base metal (e.g., iron). By coating the iron with another metal (like chromium or nickel), it creates a barrier that protects the iron from moisture and air, which are necessary for rust formation.

5. **Conclusion**: Therefore, electroplating prevents rusting and corrosion of the metal object being plated. This is a significant advantage of the electroplating process.

**Final Answer**: Electroplating prevents rusting and corrosion of metals.
